SolarEdge Solar Inverters & Power Optimisers Error messages

SolarEdge inverters come standard with 12 year warranties, this is far longer than a standard solar inverter warranty of 5 years.
SolarEdge power optimisers come standard with a 25 year warranty, that is the same length as the performance warranty on the solar panels they are connected too.

The Limited warranty for SolarEdge solar power inverters and the solar panel optimisers does not cover labour costs of a third party to travel to your property and replace or repair the units, however Gold Coast Solar Power Solutions are a SolarEdge Certified Installer and as a certified installer SolarEdge will cover our labour costs for any warranty work.

Huawei SUN2000L Solar Inverters

September 27, 2024 Simon Rogers No Comments

Huawei SUN2000L Solar Inverters

Huawei entered the solar inverter market in 2013. Huawei sold mainly to China and the wider Asian and European markets and are relatively unknown in Australia.

The Huawei SUN2000L inverter range (2 – 5kW) are compact and have the ability to function as a stand alone string inverter with partial or full panel optimisation. The SUN2000L inverters have a built-in DC coupling battery interface which is compatible with LG Chem RESUH batteries. Please note that it does not have Emergency Power Supply so in the event of a blackout your lights will not stay on.

Huawei SUN2000L inverters come with a standard 5 year warranty

If you experience an issue on a Huawei Solar Inverter, the manual shutdown procedure is useful in fixing some errors. There are also other faults that require other procedures.

Huawei Solar Inverter data sheet

Huawei data sheet

For convenience, we have put together a list of error messages, possible causes and remedies.

Alarm severities are defined as follows:

Major: The SUN2000L enters Shutdown mode and disconnects from the power grid to stop generating power after a fault occurs.
Minor: Some components are faulty but the SUN2000L can still connect to the power grid and generate power.
Warning: The SUN2000L output power decreases due to external factors.

Alarm ID	Alarm Name	Alarm Severity	Possible Cause	Suggestion
2001	High String Input Voltage	Major	The PV array is incorrectly configured. Excessive PV modules are connected in series to the PV string, and therefore the open-circuit voltage exceeds the maximum inverter input voltage.	Reduce the number of PV modules connected in series to the PV string until the PV string open-circuit voltage is less than or equal to the maximum inverter input voltage. After the PV array is correctly configured, the inverter alarm disappears. The following is the mapping between PV strings and alarm cause IDs: – Cause ID 1: string 1 – Cause ID 2: string 2 Contact your installer
2011	String Reversed	Major	The PV string is reversely connected.	Check whether the PV string is reversely connected to the SUN2000L. If so, wait until the solar irradiance declines at night and the PV string current reduces to below 0.5 A. Then, turn off the DC switch and correct the PV string polarity. The following is the mapping between PV strings and alarm cause IDs: – Cause ID 1: string 1 – Cause ID 2: string 2 Contact your installer
2032	Grid Failure	Major	Cause ID = 1 – The power grid experiences an outage. – The AC circuit is disconnected or AC switch is off.	1. Check the AC voltage. 2. Check that the AC power cable is connected and that the AC switch is ON.
2033	Grid Undervoltage	Major	Cause ID = 1 The grid voltage is below the lower threshold or the low voltage duration has lasted for more than the value specified by LVRT.	1. If the alarm occurs accidentally, the power grid may be abnormal temporarily. The SUN2000L automatically recovers after detecting that the power grid becomes normal. 2. If the alarm occurs frequently, check whether the grid voltage is within the acceptable range. If not, contact the local power operator. If so, modify the power grid overvoltage and undervoltage protection thresholds with the consent of the local power operator. 3. If the fault persists for a long time, check the connection between the AC switch and the output power cable.
2034	Grid Overvoltage	Major	Cause ID = 1 The grid voltage exceeds the higher threshold or the high voltage duration has lasted for more than the value specified by HVRT.	1. Check whether the grid connection voltage exceeds the upper threshold. If so, contact the local power operator.2. If you have confirmed that the grid connection voltage exceeds the upper threshold and obtained the consent of the local power operator, modify the overvoltage and undervoltage protection thresholds.3. Check whether the peak grid voltage exceeds the upper threshold.
2035	Grid Overfrequency	Major	Cause ID = 1 Power grid exception: The actual grid frequency is higher than the local power grid standard.	1. If the alarm occurs accidentally, the power grid may be abnormal temporarily. The SUN2000L automatically recovers after detecting that the power grid becomes normal. 2. If the alarm occurs frequently, check whether the grid frequency is within the acceptable range. If not, contact the local power operator. If so, modify the grid overfrequency protection threshold with the consent of the local power operator.
2037	Unstable Grid Frequency	Major	Cause ID = 1 Power grid exception: The actual grid frequency change rate does not comply with the local power grid standard.	1. If the alarm occurs accidentally, the power grid may be abnormal temporarily. The SUN2000L automatically recovers after detecting that the power grid becomes normal. 2. If the alarm occurs frequently, check whether the grid frequency is within the acceptable range. If not, contact the local power operator.
2039	Output Overcurrent	Major	Cause ID = 1 The grid voltage drops dramatically or the power grid is short-circuited. As a result, the inverter transient output current exceeds the upper threshold and therefore the inverter protection is triggered.	1. The SUN2000L monitors its external working conditions in real time. The SUN2000L automatically recovers after the fault is rectified.2. If the alarm occurs frequently and affects the power production of the PV plant, check whether the output is short-circuited. If the fault persists, contact your supplier.
2040	Output DC Component Overhigh	Major	Cause ID = 1 The DC component of the SUN2000L output current exceeds the specified upper threshold.	1. The SUN2000L monitors its external working conditions in real time. The SUN2000L automatically recovers after the fault is rectified.2. If the alarm occurs frequently, contact your supplier.
2051	Abnormal Residual Current	Major	Cause ID = 1 The insulation impedance of the input side to PE decreases when the SUN2000L is operating	1. If the alarm occurs accidentally, the external power cable may be abnormal temporarily. The SUN2000L automatically recovers after the fault is rectified. 2. If the alarm occurs frequently or persists, check whether the impedance between the PV string and ground is below the lower threshold.
2061	Abnormal Grounding	Major	Cause ID = 1 – The PE cable for the SUN2000L is not connected. – The voltage between the SUN2000L neutral wire and ground exceeds the upper threshold.	1. Check that the PE cable for the SUN2000L is connected properly.2. Check that the voltage between the SUN2000L neutral wire and ground is within the normal range. If an isolation transformer is connected, set OFF due to abnormal grounding to Disable by referring to 7.4.5.3 Feature Parameters.
2062	Low Insulation Resistance	Major	Cause ID = 1 – The PV string is short-circuited to PE. – The PV string is installed in a moist environment for a long time.	1. Check the impedance between the PV array output and PE, and eliminate short circuits and poor insulation points.2. Check that the SUN2000L PE cable is correctly connected.3. If you confirm that the impedance is less than the default value in a cloudy or rainy environment, reset Insulation resistance protection.
2063	Overtemperature	Major	Cause ID = 1 – The SUN2000L is installed in a place with poor ventilation. – The ambient temperature exceeds the upper threshold. – The SUN2000L is not working properly.	1. Check the ventilation and ambient temperature at the SUN2000L installation position.2. If the ventilation is poor or the ambient temperature exceeds the upper threshold, improve the ventilation and heat dissipation.3. If both the ventilation and ambient temperature meet requirements, contact your supplier.
2064	Device Fault	Major	Cause ID = 1–12 An unrecoverable fault occurs on a circuit inside the SUN2000L.	Turn off the AC output switch and DC input switch, and then turn them on after 5 minutes. If the fault persists, contact your supplier.
2065	Upgrade Failed	Major	Cause ID = 1–4 The upgrade does not end normally.	1. Perform an upgrade again. 2. If the upgrade fails several times, contact your supplier. 3. Check that the DC power supply is connected.
61440	Monitoring Unit Faulty	Minor	Cause ID = 1 The communication module is faulty.	Contact your supplier to rectify the fault.
2067	Faulty Power Collector	Major	Cause ID = 1 – In Grid Connection with Zero Power mode, the energy meter communication is interrupted. – In Maximum Use of Self-Produced Power mode, the energy meter communication is interrupted.	1. Check that the preset energy meter model is the same as the actual model.2. Check that the preset communications parameters for the energy meter are the same as the actual configurations.3. Check that the energy meter is powered on and the RS485 communications cable is correctly connected.
2068	Battery Abnormal	Minor	Cause ID = 1 – The battery is faulty. – The battery communication is interrupted. – The battery switch trips when the SUN2000L is running.	1. Check that the communications cable and power cable between the SUN2000L and the battery are properly connected.2. Check that the battery switch is turned on properly.3. Turn off the AC output switch, DC input switch, and battery switch, and then turn them on after 5 minutes. If the fault persists, contact your supplier.
2075	Peripheral Port Short Circuit	Warning	Cause ID = 1 The SUN2000L Alarm port is short-circuited when supplying 12 V power to peripheral.	1. Turn off the AC and DC switches on the SUN2000L and disconnect the peripheral from the Alarm port. Then power on the SUN2000L again and clear the alarm manually. If the alarm persists, contact your supplier to rectify the fault. If the alarm is cleared, it indicates that the port on the SUN2000L is normal. Then check that the pins in the power port on the peripheral are not short-circuited.2. Replace the peripheral, and then start a self-check to check that the port functions properly.

Bosch BPT-S Solar Inverter faults and operational manual

Bosch entered the solar market with the manufacture of premium solar panels. In 2013 they stopped manufacturing solar panels and entered the solar market again with their Bosch BPT-S string inverters. There were flaws in these inverters as they were not as efficient for Australian conditions as they were for European conditions. In January 2016, Bosch discontinued their manufacture. These inverters came with the standard 5 year warranty. Warranty claims are being honoured by Bosch.

If you experience an issue on a Bosch Solar Inverter, the manual shutdown procedure is useful in fixing some errors. There are also other faults that require other procedures.

Geoprotek Solar Inverter common faults and user manual

Geoprotek solar inverters have been introduced to the Australian market by S.E.A. – Solar Energy Australia and the inverters came with the standard with a 5 year warranty.

If you experience an issue on a Geoprotek Solar Inverter, the manual shutdown procedure is useful in fixing some errors. There are also other faults that require other procedures.

Error Message	Possible cause	Remedy
Grid Fault	The grid voltage or frequency is out of the permitted range.	•The GS INVERTER will reset automatically when the grid returns to normal operation. •Test the grid voltage, frequency, and grid Connection on GS INVERTER. •Make sure grid voltage and frequency meet the specifications. •If the grid voltage is within the acceptable range, but the error is still displayed, discuss the proposed parameters with the service line.
PV Over Voltage	The DC input voltage at the GS INVERTER is too high.	•Disconnect the GS INVERTER from the PV array immediately. • Check the DC voltage of the strings to ensure that they comply with the maximum input voltage of the GS INVERTER before connecting it to the PV array again.
Ground I Fault	The leakage current of the GS INVERTER and the PV array is too high. This can be caused by a sudden fault in the connection to ground, a fault current or a malfunction.	•Check the strings for ground faults. Unplug the PV array from the DC-input, check the AC peripheral system. •After the cause is cleared, plug PV in again and check the status of Inverter.
Isolation Fault	Earth leakage or insulation fault on the DC side. Or phase and neutral conductor interchanged.	•Check PV array and DC cabling. •Check the phase on the AC mains supply. •Check the impedance between the DC (+) and DC (-) and earth ground. The impedance must be larger than 8MΩ. •If the error is still displayed, please contact the service line.
Over Temperature	The internal temperature of GS INVERTER is too high Insufficient air circulation	•Ensure air can circulate at the side of the GS INVERTER. •improve ventilation around the inverter. •If it is not effective, the temperature sensors fails, please contact the service line.
No Utility	Grid is not connected; check the AC connection by multi-meter.	• Check AC installation and grid connection. • Check whether there is a general power failure. • Check breaker between inverter and grid; if it is tripped, DO NOT CLOSE again, replace the inverter.
Impedance Fault	The grid impedance at the connection point of the GS INVERTER is too high.	•Observe the error for 30 seconds, check if it works normally. •Check the wires between inverter and grid. Change larger wires if necessary. •If the error is still displayed, please contact the service line for further assistance.
Consistent Fault	It may cause by the reading difference between main and redundant controllers.	•Switch off the DC isolator switch and PV array isolators. •Switch off solar supply main switch. •Disconnect DC (+) and DC (-) from the input for one minute and reconnect it again. •Switch on the solar supply main switch. •Switch on the DC isolator switch and PV Array isolators. •If it does not work, please contact service line.
DC Curr Mismatch	The reading difference of output DC current between main and redundant controllers.
GFCI Mismatch	The reading difference of GFCI value current between main and redundant controllers.
Grid V Mismatch	The reading difference of Grid V between main and redundant controllers.
Grid F Mismatch	The reading difference of Grid F between main and redundant controllers.
Grid Z Mismatch	The reading difference of Grid impedance between main and redundant controllers.
Sci Fault	Communication error between main and redundant controllers.
CPU Ver Mismatch	The reading difference of firmware version between main and redundant controllers.
Device Fault	It may be caused by improper operation of the circuit.	•Switch off the DC isolator switch and PV array isolators. •Switch off solar supply main switch. •Disconnect DC (+) and DC (-) from the input for one minute and reconnect it again. •Switch on the solar supply main switch •Switch on the DC isolator switch and PV Array isolators. •If it does not work, please contact service line
Relay Failure	It may be caused by the failure of output relay.
DC INJ High	It may be caused by the DC output injection was too high

What is MPP or MPPT?

September 27, 2024 Simon Rogers

What is a MPP?

The solar power MPP The conditions that solar panels work under out in the real world are constantly changing, and as these conditions change the voltage and current produced by the solar panels constantly change as well. The power being produced by a solar panel is proportional to the current (I) and voltage (V) of the solar panel as can be seen on the graph to the right. This a typical IV curve of a 224W solar panel and as can be seen the spot on the curve which both the voltage and current are at their highest is the maximum power point, or MPP.

What is a MPPT?

To get the most power possible out of a solar panel or a bank of solar panels it is imperative that this maximum power point is constantly tracked by the solar inverter or charge controller as it is constantly changing. A solar inverter or charge controller that can track this maximum power point is called a MPPT which stands for Maximum Power Point Tracker. Most solar power inverters 3kW in size or larger have multiple MPPT’s so they can get the maximum power from solar panels which have different voltages or current, this may be from solar panels facing a different direction, banks of solar panels of a different amount or types amongst other things.

When solar panels are connected to a MPPT solar inverter they are usually connected in series, which means each solar panel is connected from positive of one panel to the negative of the next. When wired this way the voltage of each panel adds together but the current stays at that of one panel; so if 10 of the 224W panels shown in the graph above were wired in series the horizontal axis for current would stay the same but the vertical axis for voltage would be multiplied by the 10 panels, so the series string of panels would have a voltage of 400V. The worst thing about having solar panels wired in series is that every panel wired up together or stringed together like this is only ever as good as the weakest link.

How solar panels are fixed to your roof

September 27, 2024 Simon Rogers

How solar panels are fixed to your roof

When solar panels are fixed to your roof obviously it’s very important that they are installed correctly, because if they’re not we have two potentially major issues:

The panels may be dislodged in high winds – An Upforce rather than a Downforce
Water may enter your home in heavy rains

I’m sure you’d agree that both these issues are unacceptable!

So let’s have a look at how the solar panels are fixed to your roof and how we ensure the installation remains watertight, on both tile and sheet metal type roofs.

How solar panels are installed on a tile roof

Installing solar panels on a tiled roof takes a bit longer as the stainless steel brackets are attached underneath the tiles and are screwed into the trusses. In order to do this the installer will need to move the tiles to expose the roof trusses to enable them to screw in the stainless steel brackets. Once this has been done the tile is slid back into position with the stainless steel bracket showing. The rails are then mounted to the stainless steel brackets and the panels are mounted to the rails.

All cable penetration through the tiles have waterproof protection with Dektite, as per the picture.

We highly recommend that you have extra tiles on hand in case, although rare, tiles break.

How solar panels are installed on a tin/sheet metal roof

To install solar panels on a tin roof we use the existing screw holes so no new screw holes are made. An ‘L’ shape bracket which has rubber feet is then screwed into existing penetration and this then forms a waterproof seal. The rails are then mounted to the ‘L’ shape brackets and the panels are mounted to the rails.

All penetration through the tin roof is done on the high point of the tin profile rather than the low point so there is no water leaks. Cable penetration also has waterproof protection with Dektite, as per the picture.
